This pokey plant, with numerous health benefits, is named after the hedgehog. Its spiky appearance belies its gentle medical relief. The plant is echinacea, a traditional Native American medicinal plant. Various Native American tribes have used it to treat the cough, relieve toothache, and as a natural painkiller. Recent studies have revealed that echinacea can also boost immune function, reduce pain, and its antiviral properties. The petals, leaves, and roots are all used medically. Hedgehogs are funny and sweet looking, but echinacea’s health benefits are no joke.
